Hi,
I am using RSPerl package on Ubuntu and Apache2 web server. It is my first
experience with R language :-)
I have the next code embedded into a Perl CGI:
use R;
use RReferences;
my @x;
&R::initR("--silent","--no-save");
&R::library("RSPerl");
@x = &R::call("rnorm", 10);
&R::call("plot", [EMAIL PROTECTED]);
The CGI works but no plot is shown.
Apache2 web server log says:
[Sun Jun 22 12:01:41 2008] [error] [client 127.0.0.1] Error in pdf() :
unable to start device pdf, referer: http://localhost/html/proveta.html

[Sun Jun 22 12:01:41 2008] [error] [client 127.0.0.1] Caught error in
R::call(), referer: http://localhost/html/proveta.html
However, if I use R directly plots are correctly shown.
Can anybody help me?
Thanks!
